SSH is a secure shell communication, is a secure protocol and the most common WAY of administering remote servers safely, relatively very simple and inexpensive to implement. A single SSH connection can host multiple channels and HENCE can transfer DATA in both directions. SSH WORKS on Port No. 22, and it is the default port NUMBER. However, it can be configured to point to a new port number, but its not recommended. In local host, password is required in SSH for security and in a situation where password less communication is not set.
